SCHOTT Filter Calculator

Online transmission calculator for SCHOTT optical color glass filters


Our online SCHOTT filter calculator allows you to individually calculate and analyze the transmission curves of nearly all SCHOTT color glass filter materials, which makes it easy to find out the best optical color glass filter for your application. We provide this helpful tool to you for free.


Calculation Parameters

Select filter type:

Enter the filter thickness:

mm ?Please consider that it is not recommended to choose filter thicknesses below 1mm because compliance with the material's transmission specifications at lower thicknesses isn't safe anymore.                                                 

Transmission curve output:

Spectral transmittance ?Choose this option to see the transmission under real-world conditions: This option includes surface reflection losses based on a single filter used in air.                                                         
(Surface reflection-losses included)
Internal transmittance ?Choose this option to see the internal transmission of the filter. This option does NOT consider the surface reflection losses which under normal conditions occur. The internal transmission is essential to know for the design of cemented filter combinations.                                                         
(Internal transmittance, surface reflection-losses NOT included)
Best scale factor for transmission axis (Y-axis zoom) ?This option allows the automatic best scaling depending on the maximum transmission within the measuring range. If, for example, maximum transmission of 10% is reached within the measuring range, the Y-axis, which is the transmittance, is scaled to a value range of 0-10% to allow a more accurate analysis of the transmission in wavelength ranges with lower transmissions.
